Create and share a folder with full access over LAN

[M_S_T]

I've created a program that communicates to duplicated programs using a text file in a shared folder over a lan network.

 

My problem is, I need my program to create and share the folder with the text file, so I don't have to create it manually.

 

I'm programming with vb6 and all the OS's on my lan are WindowsXP.

Any help would be greatly appreciated.
